To all whom it may concern:

Be it known that I, AUoUs'r RIEBE, a subject of'the King of Prussia, residing at 34. and 35 Huttenstrasse, Berlin, in the King- 'dom' of Prussia, Germany, have invented certain new and useful Improvements in Ball-Bearings, of which the following is a full, clear, and exact description.

- The invention relates ifi a ball bearing of that class in which the .t'alls' are arranged between two concentricrings provided with grooves, said balls, being maintained at a certain distance from each. other by means of an annular movable cage. In ball bearings of this character as heretofore constructed, the cage is made entirely of sheet metal such as iron plate or other comparatively hard metal. Thuswhenthese bean ings are Working there results considerable noise, friction and Wear, which circumstances have led to the ca e being constructed of soft metal, such or exam le as an anti-friction metal, alloy or the like, thereby lessening the friction and noise. If the cage is constructed entirely of soft metal then in order to obtain the necessary strength it must .be made of considerable thickness,

thereby of course increasing the Weight and metal or other soft material such as leather,

fiber or the like, that is, of such materials as contribute to reduce the noise and -friction. By reason of this combination the cage is relatively speaking light and the balls turn in their ca e Without noise and with very slight friction while if the ca e becomes heated so that the lining'is so ened or melted then the hard 'metal casin or armoring is ca able of maintaining the alls at a suitable istance from each other thus permitt'ng the bearing to continue to Work properly until another lining is substituted.

The invention will now be described withl reference tothe accompanying drawings in Whicl1--- Figure 1 is a side elevation of a complete bearing, Fig. 2 is a side elevation of a portion of the bearing drawn to an enlarged scale, Fig. 3 is a cross section on the lines 13-13 of Fig. 2.

Like parts are indicated by similarletters of reference in theseveralfigures.

a and b represent the outer and inner rings of the bearing, 0 represents the balls working in the circular track or race of these rings,d represents an armoring or casing made of sheet metal such as iron plate or is an'in-ner lining of anti-friction metal which is held in this armo-ringor casing by any suitable means and incloses the balls.

The armoring or casing shown consists of twoannular oppositely situated parts (i which are connected together I) rivets f other comparatively hard material and c or other fixed or removable fixing means and in each of these parts grooves or re cesses y are formed bystamping or otherwise andserve toreceive the lining e. lhe lining e isformed by pouring metal into the hollow space of the armoring orcasing d after having'inserted the balls and by the aid of a suitable mold or it may be eiiected in any other suitable manner. Should the bearing become heated and the lining e be burned out or inlted the balls will-be still" separated from each other by the rivets 7'. The bearing will hence remain in working condition whether the lining is in place or not, although its efficiency may. not be as great as though the lining were intact. In place of the rivets any other suitable means for separating the balls may be employed. Instead of antifriction metal an inner linin e of fiber or other suitable material may be substituted therefor.

It may be remarked that, the shape and the method of constructing the armoring 'or casing d and lining e may be varied with present invention.

'What I claim as my invention and desire to secure by patent is:

' 1. A cage for ball. bearings, having between each two adjacent balls two indeout departing from the principle of the pendent means for separating them, one of such means consisting -of arelatively soft material extending normally between each two adjacent balls a sufiicient distance to.

hold the balls separated in use, and the other of said means constituting an emergency device adapted to hold the balls separated when the first of said means is worn out or melted.

2. A cage for ball bearings, having between each two adjacent balls two independent means for separating them, one of such means consisting of soft metal extending normally between each two adjacent balls a sutlicient distance to hold the balls separated in use, and the other of said means constituting an emergency device adapted to hold the balls separated when the first of said means is worn or melted, and comprising hard metal members of proper proportions to separate the balls.

3. A cage for ball bearings, having between each two adjacent balls two independent means for separating them, one of such means consisting of soft metal extending normally between each two adjacent balls a suficient distance to hold the balls separated in usetand the other of said means constituting an emergencydevice adapted to hold the balls" separated when the first of said means is worn or melted, and comprising hard metal members of-proper proportions to separate the balls, and an annular casing of hard metal supporting both said means.

' 4. A cage for ball bearings, having an annular casinjgof hard metal, and a lining of softer material supported upon said casing, said lining extending between the balls to a sufficient extent to keep'them separated in use.

5. A cage for ball bearin s, having an an nular casing of hard meta and a lining of softernietal supported upon said casing,

said lining extending between the balls to a sufficient extent to keep them separated in use.

tending between the balls and keeping thelatter separated in use.

7 A cage for ball bearings, having an annular casing. and an annular lining, the lining normally constituting the means for separating the balls, and having a recess for each ball, and between such recesses portions extending between each two adjacent balls.

8. A cage for ball bearings, having an annular casing of hard metal, and having an annular soft metal lining formed as a single part and having a recess for each ball and portions between said recesses for separating each .two adjacent balls.

9. cage for ball bearin s, having an annular casing of hard meta, and having an annular soft metal lining formed as a single part, and having a recess for each ball and portions between said recessesfor separating each two adjacent balls, and hard metal parts extending between each two adjacent balls and designed to separate the balls after said lining is worn or melted.

In witness whereof, I. have hereunto signed my name in the presence of two subscribing witnesses.

AuGUsT RIEBE.
